Identify the percent, amount, and base in this problem: 30% of what number is 75?

To find percentage, you move the decimal to the left twice on the percentage, then multiply by your number. However, we are not finding 30% of 75. 75 IS the percentage. So, what we know is:

x * .30 = 75

We can do the reverse of multiplication to solve this:

75 ÷ .3 = 250

30% of 250 is 75.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
